Subject:
Arkansas Nuclear One - Unit 1 Docket No. 50-313 License No. DPR-51 Reactor Vessel Materials Surveillance Program at DB-1 (File:
1510)
Gentlemen:
In regard to your letter of June 16, 1980, which concerned the reactor Vessel surveillance program of Arkansas Nuclear One, Unit No.1 (ANO-1),
we question the necessity of an inmediate change of Technical Specifica-tion 4.2.8.
According to this specification, if at any time Davis-Besse, Unit No.1 (DB-1) fails to maintain a cumulative reactor utilization fac-tor of greater than 65% beginning one year after attainment of commercial operation at 100% power, we must submit a report to the NRC within 90 days after the occurrence to either justify the continued operation of ANO-1 or propose an alternative surveillance program.
The previous occurrence has shown that the current procedure is adequate to maintain the reactor vessel material surveillance program. The eval-uation, which accompanied your letter, states that the relatively low
- utilization factor in the early life of DB-1 will not adversely affect the ANO-1 surveillance schedule. We, therefore, conclude that a Techni-cal Specification which would provide limiting condition F DB-1 opera-tion should not be proposed at this time.
Very truly yours, b&0 David C. Trimble Manager, Licensing
